125

(d)
What is the percentage increase in the number of people who will hear the story from one Generation to another? show your work

Answer 1

To calculate the percentage increase in the number of people who will hear the story from one Generation to another, we can use the following formula:

Percentage Increase = ((Number of People in Later Generation - Number of People in Earlier Generation) / Number of People in Earlier Generation) * 100

For the increase from Generation 1 to Generation 2:
((25 - 5) / 5) * 100 = (20 / 5) * 100 = 4 * 100 = 400%

For the increase from Generation 2 to Generation 3:
((125 - 25) / 25) * 100 = (100 / 25) * 100 = 4 * 100 = 400%

Therefore, the percentage increase in the number of people who will hear the story from one Generation to another is 400% for both transitions.
